I Application filed May 7, 1915, Serial No. 26,581. Renewed August 9, 1916. Serial No. 114,072.

To all whom it may concern Be it known that I, FRANK SKALLA, a citizen of the United States, residing at Niles, in the county of Berrien and State of Michigan, have invented new and useful Improvements in Bowling-Pins, of which the following is a specification.

The invention relates to bowling pins, and more particularly to the class of composite bowling pins.

The primary object of the invention is the provision of a pin wherein the body thereof is materially reinforced, the said body being formed from a composition, while the reinforcement is preferably made in the form of a hard wood core and is extended through the neck and bowl of the pin throughout the longitudinal extent thereof.

Another object of the invention is the provision of a pin of this character wherein the construction thereof is of novel form to render it firm, yet soft and with a certain amount of yielding quality to cushion when hit by a ball or knocked against the alley or floor to minimize sound, and thus reduce the noise resultant from the playing of the game.

A further object of the invention is the provision of a pin of this character wherein the same can be rendered the proper weight,

and is easily made.

A still further object of the invention is the provision of a pin of this character which is simple in construction, reliable and efficient in its purpose, strong, durable, and

inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

In the drawing :-Figure 1 is a side elevation of a pin constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view thereof. Fig. 3 is a view similar to' Fig. 2, showing a slight modification.

Similar reference characters indicate corresponding parts throughout the several news in the drawing.

Referring to the drawing in detail, A designates the shell or body of the pin, preferably made from a composition composed of compressed cork and a binding gum, and includes the neck 5 and bowl 6, both being of hollow formation to receive therein a hard wood core 7 which extends entirely through the body centrally thereof.

Disposed concentrically about the core 7 in the space or hollow in the neck and bowl is a soft wood filling 8, the core 7 being designed to reinforce the body of the pin.

In Fig. 3 there is shown a slight modification of the pin, wherein the body B is constructed similarly to the body A hereinbefore set forth, and has centrally therein a hard wood core 9, While the neck and bowl 10 and 11 are formed with the respective hollow spaces 12 and 13 concentrically about the said core 9.

The process of putting the core in the body of the pin is as follows: A mold is employed which is filled with half of the composition matter that it takes to make the pin, and then the core is coated with adhesive and placed on top of the composition which is now in the mold, and thereafter the other half of the composition is placed upon the top of the core, and finally a die is used which will press out the shape of the pin, pressure being applied to the sections of the die until both edges thereof come together, and finally retaining clamps are engaged with the die so that the same can be placed in an oven when containing the pin for the drying thereof. Should the soft wood filling 8 be used, the same is placed upon the core 7 prior to the positioning of the same in the half of the composition within the mold.

From the foregoing description, taken in connection with the accompanying drawing, the construction of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is 1. A bowling pin comprising a hollow 10 into the neck and bowl thereo and a core of uniform cross sectional area throughout its length extending through the body into the neck and bowl thereof and terminating flush with the bottom and head of the body.

2. A bowling pin comprising a hollow unbroken body made from a composition, a core of uniform cross sectional area throughout its length extending through the body and terms.-

natingflush with the bottom and head of the body, and asoft filling centrally disposed about the core in the bowl and neck of said body.

In testimony whereof I aflix my signa- 15 two witnesses.

ture in presence of FRANK SKALLA.
